Dietary Cholesterol Clearance Mechanisms Remain Unchangedhttps://www.live-feeds.com/feed/how-long-term-dietary-cholesterol-can-slow-down-its-own-clearance-by-liver-cellshttps://www.live-feeds.com/feed/how-long-term-dietary-cholesterol-can-slow-down-its-own-clearance-by-liver-cells#u38415Tue, 11 Aug 2026 00:21:10 +0000Liver cells slow the clearance of long-term dietary cholesterol by activating Ral proteins through increased RAS activity. This specific pathway directs low-density lipoprotein receptors to lysosomes for degradation, blocking their ability to recycle. The process operates independently of PCSK9 or transcriptional regulation. While recent research explores protein balance and methionine intake for longevity in mice, these findings do not alter the established RAS-Ral axis mechanism that inhibits cholesterol clearance in the liver.Why it mattersCholesterol clearance is essential for maintaining Dietary cholesterol suppresses liver cell clearance via Ral protein activationhttps://www.live-feeds.com/feed/how-long-term-dietary-cholesterol-can-slow-down-its-own-clearance-by-liver-cellshttps://www.live-feeds.com/feed/how-long-term-dietary-cholesterol-can-slow-down-its-own-clearance-by-liver-cells#u32895Wed, 05 Aug 2026 12:05:29 +0000Long-term dietary cholesterol intake slows its own clearance by activating Ral proteins through increased RAS activity. This mechanism directs low-density lipoprotein receptors to lysosomes for degradation, which prevents the receptors from recycling. This process occurs independently of transcriptional regulation or PCSK9. While other dietary factors like TMAO and high salt intake are linked to cardiovascular issues, the specific pathway for cholesterol clearance inhibition remains centered on the RAS-Ral axis in liver cells.Why it mattersLiver cells use low-density lipoprotein receptors to r Chronic Dietary Cholesterol Impairs Liver Clearance via Ral Pathwayhttps://www.live-feeds.com/feed/how-long-term-dietary-cholesterol-can-slow-down-its-own-clearance-by-liver-cellshttps://www.live-feeds.com/feed/how-long-term-dietary-cholesterol-can-slow-down-its-own-clearance-by-liver-cells#u22302Fri, 03 Jul 2026 02:36:11 +0000Long-term dietary cholesterol intake activates Ral proteins by increasing RAS activity. This process routes low-density lipoprotein receptors (LDLR) to lysosomes for degradation. The mechanism inhibits receptor recycling independently of PCSK9 or transcriptional regulation.What's confirmed:Chronic dietary cholesterol activates Ral proteins by increasing RAS activity.The Ral-dependent pathway routes LDLR to lysosomes for degradation and inhibits its recycling.Ral activation engages the endocytic RalBP1-REPS1 complex to promote LDLR internalization.The lysosomal protease cathepsin A (CTSA) degra
